IMPROVEMENT IN S'l'EAM-WHEELS.

The Schedule referred toln these Pateuennd making page of the um..

Tdall whom it may concern:

Be it known that I, Jona N rcoLAUs Pomxnn'r, of

I Greenfield, in the county of Highland and State of Ohio, have inventeda new and improved Steam'Wheel; and

I do hereby declare that the following is a Tull, clear, and exactdescription thereof, which will enable'others skilled in the art to makeand use the saine, reference. being had to the accompanying drawingforming part ut this specification.

llhis invention relates to improvements in wheels tol -be propelled bysteam, and consists in the application to a hollow shattoi a-c.'1sedwheel wit-h buckets or vaines ot"pecnl iar arrangement, and a pair ofradial dischargiiig-arms, the latter arranged for obtaining thereact-ing force of the steam after its 'action on the vanes of thc wheelin a direct manner, to which it isA4 admittedfrom below by dischargingtire-steam ohliqnely-npon the surthceofwater in a tank surrounding theshaft above the wheel, all as hereinafter more fully specified.

' AFigure 1 is a sectional elevation of my ixnprovtall wheel, and

Figure 2 is a plan of the bottoni with apart broken away.

A is the case or cnrb of the wheelulisk, attached to the hol-low shaft Ewithin the case, and hav-ing 4a rim, F, at the periphery, projectingdownward.

. The bottom of the wheel ls open, except around' but near thelowcredges' they are .curved or inclined from the bottom .npwardjnthedirection ofthe movement of thewhcel, at such' an angle as will beperpendicular, or nearly so, to the oblique,steam-pipes I, by

which the steam' is admitted to the buckets through the bottom of tliewheel, so that it will strike thel snr face upon which itacts in amannerto have the. greatlllevsteam passes into the shaft E after acting .uponthev buckets, and rises to the hollow radial arms K, terminating in`dischurging-normes L, t inclined rearward and downward, andrevolving'above the surface of water M- in a tank, N, Asurrounding theupper. end

of the shaft on which the' steam is discharged `in a manner to imparta.reactionary'orce to the arms; and add thereby to the ecctive forc of thewheel.

In practical propose to make the disk B of the wheel,- the rim .1?, andthe buckets in one niece by casting the whole together,

'The wheel may be set in any suitable frame, and" thc spindle Oon'w'hich it ljcsts'may have an adjustiugscrew applied to .it forraising or lowering it for adjusting-thc wheel relatively to the case.The wat/h tank mayvhave radial plates to contra-ct the tendency of thestcam'to force the water .around the tank.

Having thus described my invention,

I cla-im as new and desire to secure hy 'Letters Pat,v

cnt

The combination b t' the wheel, the case A, hollow 'shaft E, and thehollow reacting arme K I, when arranged todischarge the steam ou thesurtce ot' thc water, substantially in the manner described.
